In addition to the blower parts, Magnuson included a RTD. These companies "assume" you don't have a flash interface, so unless you make specific arrangements when you place your order, you might be sent this device so you can flash their tune, via the OBD2 port, to your ECM. It could be the actual tune file is IN the RTD, or (like I had to - I had to submit my VIN when I ordered the blower kit) you submit your vehicle information, they add it to the calibration, and then they email your tune. Then - you'd download the file to the RTD and flash the car.
So - while I have NOT worked with Edelbrock, I'm fairly certain these are the basic scenarios you'll be facing, regarding the calibration files. I do NOT think they're going to make tweaks - if you paid for a canned cal', that's what you'll get, and it will, probably, not be optimized to your specific combination. Alternatively - you could opt to pay a shop to write a custom file for you, and that might be more than the canned calibration, but you'll get the most out of your combination that way. But - as long as your combination falls under the specific conditions of Edelbrock's calibration file, your car will most likely be completely safe, but conservative.
It's a good question about re-licensing, too. I couldn't comment on that, because I've seen both. That is something you should reach out to Edelbrock (or whoever you're buying the blower kit from) to get information about. With Magnuson - the calibration file I bought included licensing the E92, so when I started writing my own tunes (I didn't say calibration, lol...), I didn't have to pay to relicense the ECM. Hopefully that makes sense. Unless the calibrator locks the file, you (as far as I've experienced) shouldn't have to re-license to write follow-up tunes. NOW - this also depends on if they are calibrating any other modules in the car (e.g. TCM, CCM), which is probably not the case, but that could be a thing, too. As an A10 car, Magnuson did not calibrate anything other than the ECM, so that's likely the case with Edelbrock. It's likely they did the minimum, as these canned tunes are, oftetimes, for CARB-type compliance, so they're going to touch the minimum, which is why, most of the time, you can custom tune these calibrations to optimize your combination.
I didn't notice if you had mods' on the car, but I would expect that the calibration from them is, strictly, going to be on a completely stock car (powertrain-mod'-wise), so if you can a CAI that requires a tune, the Edelbrock cal' will NOT work (same thing for LTs, or most other bolt-ons).
JMO.
